As Dejan said I missed the clone-node-max="8" (it defaults to the number of
nodes so it only started 2 instances of the clone)
I also missed something in the primitive which would have caused it to only
create one IP no matter what pacemaker said it had created. I tested with 8
IP's and ip address show only showed one even though it said 8 were started on
the node. You also have to have unique_clone_address="true" on the primitive.
Here's the example I tested successfully (pinged all 8 without issue from other
node):
root@Condor:~# crm configure show p_testIPs
primitive p_testIPs ocf:heartbeat:IPaddr2 \
params ip="192.168.2.104" cidr_netmask="29" clusterip_hash="sourceip"
nic="bond0" iflabel="testing" unique_clone_address="true" \
op monitor interval="60"
root@Condor:~# crm configure show cl_testIPs
clone cl_testIPs p_testIPs \
meta globally-unique="true" clone-node-max="8" clone-max="8"
target-role="Started"
root@Condor:~# crm_mon

You may want to look into the different options for clusterip_hash, nic, arp,
and what to use for cidr_netmask for the IPaddr2 primitive

This shows the primitive is unmanaged - that means the stop all wont apply
because pacemaker isn't managing the resource right now
Try:
crm(live)# resource
crm(live)resource# manage ClusterIP.144.1
crm(live)resource# up
crm(live)# configure
crm(live)configure# property stop-all-resources=true
crm(live)configure# commit
